Purpose : The purpose of this study is to analyze the correlation between the TPI Level 1 test and the performance of KPGA professional golf players. Methods : In 2019, 30 KPGA golf players attempted in the TPI Level 1 test. Their performance was then compared with the test based on the players' aggregated official records on the KPGA website, The most meaningful prize money ranking, average driving distance, fairway landing rate, and average number of putts were considered to evaluate their performance. Additionally, to obtain the average value of the players' accumulated records, the period from the first game in March 2019 to the end of October was considered. Results : The criterion for the difference between the upper group and the lower group was set based on the 9 points of the TPI Level 1 test, which showed the most significant difference. The prize money ranking stood at 63.00±51.77 in the upper group and 113.92±68.79 in the lower group in the TPI Level 1 test, the difference was significantly higher (p<.05) for the upper group (p<.05). The average driving distance was 286.15±10.06 yds for the upper group and 277.39±8.49 yds for the lower group, group, with the driving distance significantly higher in the upper group (p<.05). Further, the average number of putts for the upper group was 1.81±.02 and 1.85±.04 for the lower group, indicating a significant difference. Conclusion : A higher TPI Level 1 test score is likely to have a positive effect on performance.. As a result of the statistical values of this study, it was found that players must possess at least 9 out of 17 types of physical abilities Therefore, it can be considered that training and intervention to acquire these physical abilities are essential.

This paper proposes an efficient test wrapper design that reduces overall test time in multi-core SoC. After initial local wrapper solution sets for all the cores are determined using well-known Combine algorithm, proposed algorithm selects a dominant core which consumes the longest test time in multi-core SoC. Then, the wrapper characteristics in the number of TAM wires and the test time for other cores are adjusted based on test time of the dominant core. For some specific cores, the number of TAM wires can be reduced by increasing its test time for design space exploration purposes. These modified wrapper characteristics are added to the previous wrapper solution set. By expanding previous local wrapper solution set to global wrapper solution set, overall test time for Multi-core SoC can be reduced by an efficient test scheduler. Effectiveness of the proposed wrapper is verified on ITC'02 benchmark circuits using $B^*$-tree based test scheduler. Our experimental results show that the test time is reduced by an average of 4.7% when compared to that of employing previous wrappers.

A statistical test was carried out on the IID (Independently and Identically Distributed) assumption of the AM (Annual Maxima) data used to estimate the design wave height. The test was divided into independence (randomness) test and homogeneity test, and each test was conducted on AM data of 210 and 310 stations in coastal and inner coastal grids in typhoon and non-typhoon (monsoon) conditions. As a result of the independence test, the rejection ratios of the test are in the range of 1.8~5.3% and 1.4~6.0% for the non-typhoon and typhoon data sets, respectively. On the other hand, in the distribution difference test of typhoon data and nontyphoon data, the same distribution hypothesis was found to be rejected in the range of 47~79% according to the test method for both coastal grid and inner coastal grid. Therefore, in estimating design wave height by extreme value analysis, the estimation process by dividing the typhoon and non-typhoon data is appropriate.

To investigate the seismic performance of Y-shaped eccentrically braced frames fabricated with high-strength steel (Y-HSS-EBFs), a shake table test of a 1:2 scaled three-story Y-HSS-EBF specimen was performed. The input wave for the shake table test was generated by the ground motions of El Centro, Taft, and Lanzhou waves. The dynamic properties, acceleration, displacement, and strain responses were obtained from the test specimen and compared with previous test results. In addition, a finite element model of the test specimen was established using the SAP2000 software. Results from the numerical analysis were compared with the test specimen results. During the shake table test, the specimen exhibited sufficient overall structural stiffness and safety but suffered some localized damage. The lateral stiffness of the structure degenerated during the high seismic intensity earthquake. The maximum elastic and elastoplastic interstory drift of the test specimen for different peak ground accelerations were 1/872 and 1/71, respectively. During the high seismic intensity earthquake, the links of the test specimen entered the plastic stage to dissipate the earthquake energy, while other structural members remained in the elastic stage. The Y-HSS-EBF is a safe, dual system with reliable seismic performance. The numerical analysis results were in useful agreement with the test results. This finding indicated that the finite element model in SAP2000 provided a very accurate prediction of the Y-HSS-EBF structure's behavior during the seismic loadings.

Purpose: The aim of this study was to investigate the current status of the use of neglect test tools and the awareness for egocentric neglect (EN) and allocentric neglect (AN). Methods: A survey questionnaire was distributed to occupational therapists attending continuing education at the Daegu-Gyeongbuk branch on April 16. A total 143 responses were collected, and with the exception of 5 incomplete responses, 138 of them were analyzed. Results: The most commonly used unilateral neglect test tools were the line bisection test (86 responses, 62.3%), cancellation test (35 responses, 25.4%), copy and drawing test (7 responses, 5.1%). In a follow-up survey of 86 respondents who used line bisection tests as the most commonly used test, the majority (82 responses, 95.3%2) were found to use the 20-line test paper. In question about the familiarity and education experience for test manual, only 20 responses (23.2%) and 3 responses (3.5%) answered 'Yes'. In a question about the experience of a manual and the article for the manual, 25 responses (29.1%) answered 'Yes'. In the question regarding the separation of EN and AN on the unilateral neglect test, 44 responses (31.9%) were 'distinction' and 94 responses (68.1%) were 'no distinction'. Conclusion: Information on the guidance and interpretation of the line bisection test is lacking and the concept of EN and AN was insufficient.
